Phys.org / ALMA catches a dying star mid-transformation, with a ring from its last outburst
Astronomers have used radio observations from the Atacama Large Millimeter/submillimeter Array (ALMA) to catch a dying star in the middle of a dramatic transformation, and the data show a ring that records its final outburst. ...
Medical Xpress / The bacteria on your tongue could be linked to your brainpower
Whether you're a quick or slow thinker depends on several factors, such as the efficiency of the brain's wiring and the amount of gray matter in specific control centers. But there may be another, rather surprising influence, ...
Phys.org / How E. coli eavesdrops on the metabolic activity of other gut bacteria
The gut microbiome is teeming with hundreds of bacterial species and trillions of bacteria. These microorganisms influence many aspects of health, including digestion, and assist with numerous functions in the body. Gut bacteria ...
Phys.org / Replanted landscapes can look restored while soil fungi still lag behind
With up to 75% of the world's soils degraded, restoration projects try to reestablish functional and biodiverse environments to secure adequate food production, biodiversity, climate regulation and human well-being.
Phys.org / Solving the mystery behind a flightless beetle's transatlantic journey
They can't fly or swim, so why do their closest relatives appear on different continents? Grey Gustafson, an associate professor in the Department of Biological Sciences, discovered through DNA sequencing that the ancestors ...
Phys.org / Automated essay assessment can grade writing more accurately across topics, study finds
An artificial intelligence (AI) model can score English essays with improved accuracy across different writing topics, according to work published in the International Journal of Continuing Engineering Education and Life-Long ...
Phys.org / We're surprisingly close to conserving 30% of the world's land
In an effort to conserve the world's plants and animals, governments have pledged to conserve 30% of the planet by 2030. Official figures suggest that attempts to reach this target on land have stalled, but a new study led ...
Phys.org / In plants, sense of time is connected with sense of danger
Salty soil is a growing threat to crops worldwide. Hotter, drier weather has increased evaporation rates, drawing moisture from the soil and leaving behind concentrated mineral salts. At the same time, water shortages are ...
Medical Xpress / Protein modification partially reverses cancer-related muscle wasting in preclinical study
Cachexia is one of the most severe forms of muscle wasting in humans. It affects up to 80% of cancer patients and is caused by cancer cytokines—pro-inflammatory signaling molecules—that are released by the tumor cells themselves. ...
Medical Xpress / Reversing age by reprogramming gene expression networks
Every organ and tissue progressively loses function and integrity as it ages. In fact, researchers have identified "hallmarks of aging" that not only present specific processes impacted by age, but are also thought of as ...
Phys.org / Countries most vulnerable to fossil fuel phaseout generate just 6% of global output, climate analysis finds
Countries highly vulnerable to the phase-out of oil, gas and coal account for just 6% of global economic output, countries in Africa stand to benefit from their vast solar energy potential, and the economic interests of the ...
Tech Xplore / New spinning method builds electronic circuits directly inside soft, washable fibers
Electronic devices are no longer limited to conventional systems with a screen, keyboard and processing components. Over the past decades, some electronics engineers have been developing thin electronic fibers that could ...
